Omega Speedmaster Triple Calendar | Day-Date | 39mm Blue Dial | Ref 3523.80 I

The Omega Speedmaster Ref. 3523.80 is one of the most visually striking and versatile pieces in the Speedmaster lineup, combining the brand’s iconic chronograph design with a full triple calendar complication. Housed in a perfectly balanced 39mm stainless steel case, this reference features a rich blue dial that adds depth and personality, standing out from more traditional Speedmaster configurations.

The dial is where this watch truly shines—offering a highly detailed yet cohesive layout with day and month apertures at 12 o’clock, a pointer date around the outer track, and three chronograph subdials. Despite the complexity, Omega executed it in a way that remains surprisingly legible and visually balanced, giving the watch both technical appeal and everyday usability.

Powered by the reliable Omega Calibre 1151 automatic chronograph movement, this reference delivers strong performance along with the practicality of self-winding. The inclusion of the original warranty card adds an extra layer of collectibility and confidence, making this a more complete and desirable example. It’s a piece that blends functionality, standout design, and value—especially compared to more basic Speedmaster models.
